ISO 6400 performance
Olympus are overstating iso by nearly 1ev, check dpr samples for example;
GH2 ISO1600, 1/640
OMD ISO3200, 1/800.
The omd is the g3 sensor but in a gyro mechanism and overstated iso.
I have ordered OMD for low light situations, but after seeing many posted pictures I'm not that sure I will get noticeable (if any) improvement in low light performance compared to G3, which, of course, makes sense if OMD uses the same Panasonic sensor. The DPR measurements seem to indicate that there is little difference as well: http://www.dpreview.com/reviews/olympusem5/16
If you have both cameras, what's your opinion?
